Market voices on:

The final draft submission states Indonesia has set aside 12.7 million hectares (31.4 million acres) of forest for conservation to help realise its target. The government also hopes to derive nearly a quarter of its vast energy needs from renewable sources within a decade.

"Beyond 2020, Indonesia envisions an even bolder commitment to emission reductions," said the draft submission distributed by the ministry.

Indonesia, along with several other emissions-intensive economies, had been under pressure to submit its target before the UN climate summit in Paris.

"The Indonesia baseline uses the business as usual scenario of emission projections starting in 2010, based on historical trajectory (2000-2010), projected increases in the energy sector, and the absence of mitigation actions," the submission says.

It is hoped that a new pact to cut global emissions applicable to all countries will be hammered out at the long-awaited conference.
